It is worse than we thought – by region

"In their research, [Wei-Jun] Cai and his colleagues discovered a "pH minimum zone" that occurs at a depth of approximately 10-15 meters (~30-50 feet) in the Chesapeake Bay. The pH in this zone is roughly 7.4, nearly 10 times higher in acidity (or a unit lower in pH) than what is found in surface waters, which have an average pH of 8.2. ... This zone is suspected to be due to a combination of factors, most importantly, from acids produced when bottom water rich in toxic hydrogen sulfide gets mixed upward. The team reported the findings in a paper in Nature Communications on August 28, 2017."
"As Cai analyzed the data from these cruises and another in April 2015, he noticed that the Bay's pH seemed to reach a minimum at depths between 10-15 meters. To explain this, Cai built a biogeochemical model to simulate the way oxygen is consumed and inorganic carbon and acids are produced to match the observations measured in the Chesapeake Bay. Using direct hydrogen sulfide measurements collected in the bottom waters by Luther, Cai calculated how much acid would need to be produced to explain this minimum zone."
"The team's research shows that currently the dissolving of living shells and non-living aragonite and calcite minerals has provided a self-regulating mechanism to buffer or prevent the Chesapeake Bay's bottom waters from becoming acidic."
"Built about 200 yards northeast of the first one, the second Fire Island Lighthouse stands 168 feet tall, more than double the height of its predecessor. The stone from the original lighthouse was used to construct the terrace on which the new lighthouse and dwelling were built. The base of the second tower spreads outward for increased stability, and inside, a 192-step, spiral staircase leads to the watchroom."AND
"The Annual Report of the Lighthouse Board for 1894 contains the following on Fire Island Lighthouse: “This is the most important light for transatlantic steamers bound for New York. It is generally the first one they make and from which they lay their course.” Due to this importance, the board decided to purchase for use at Fire Island a giant bivalve lens with a nine-foot diameter that the French manufacturer Henry Lepaute had displayed at the 1893 World Columbian Exhibition in Chicago. As the lens was to be fitted with an electric arc light, a coal-fired steam power plant was constructed 200 feet west of the lighthouse in 1896."AND
"For years, the first-order Fresnel lens used in Fire Island Lighthouse from 1858 to 1933 had been exhibited at the Franklin Institute, a museum in Philadelphia. In 2000, the lens was taken off display and relocated to a warehouse, prompting calls to return the lens to Fire Island. On March 27, 2007, the 9,000-pound, sixteen-foot-tall lens arrived at Fire Island National Seashore in the form of 900 pieces packed inside twenty-one crates. With funding secured, construction of a building to house the lens was completed, and the lens went on display in July 2011."Having said all that, now you'll understand the pictures better.
"At concentrations that have been estimated for the average Martian crust, germanium is below the detection limit of the [Alpha Particle X-ray Spectrometer] APXS instrument and scientists did not expect to see it. So when the data was analyzed for elements beyond the main 16 elements, the researchers were surprised to find germanium, like zinc, is at concentrations up to 100 times higher than in the average Martian meteorite, and even 300 times higher in one vein, Berger said. The new study is the first to include APXS measurements of germanium during the rover’s first 1,360 sols, according to the study’s authors. A sol is a Martian day, which is 24 hours and 39 minutes long."
“Our new president, of course, has not been in this line of work before. And I think he had excessive expectations about how quickly things happen in the democratic process. So part of the reason I think people feel we’re underperforming is because too many artificial deadlines — unrelated to the reality of the complexity of legislating — may not have been fully understood.”I doubt that will ever change, too.
"1948 (station established 1906). Active; focal plane 84 m (276 ft); white flash every 5 s. 70 m (220 ft) octagonal concrete tower with lantern and gallery, rising from the center of a 2-story masonry keeper's house. This is the second tallest Italian lighthouse, after the Laterna di Genova. The original lighthouse was nearly destroyed by retreating German troops in 1944. The ruins were demolished in 1946, and the new lighthouse was built on the design of architect Olindo Tarcione. Located on the Via Madonna della Penna in Porto di Vasto, on a prominent cape about 7 km (4.5 mi) north of Vasto."Pictures (three real, one a model)
"Despite the initially confronting visual of the toilet so close to a bed, the bathroom can be concealed by a series of sliding doors, effectively turning the space into a bedroom with ensuite."That was the second time I had ever seen the word "ensuite". The first was in the previous sentence, where it was hyphenated.

|In this case she'd have to take a bath. I'm not sure where the shower is.|
|You'd have to slide the bed over a little to get a view of the shower|
This view obtained by NASA's Dawn spacecraft during its Survey orbit illustrates the diversity and complexity of Ceres' geology. It shows familiar features: Occator Crater with its bright deposits (called faculae) of carbonates and other salts, a series of linear features (at right) called Samhain Catenae, and another large crater on the right side of the image called Kirnis. A relatively fresh crater called Lociyo, superimposed on an older crater, can be seen toward the bottom left of the picture."And here's that picture:
"1916. Active; focal plane 85 ft (26 m); white flash every 10 s. 55 ft (17 m) square cylindrical reinforced concrete tower with lantern and gallery, rising from the corner of a square concrete fog signal building; solar-powered VRB-25 aerobeacon (1998). The original 3rd order Fresnel lens is on display at the Cordova Historical Museum in Cordova. 3-story brick keeper's quarters. The lighthouse is white concrete; lantern painted red."Here are a couple more links about it:
One of the most remote of all U.S. lighthouses."

"Instead of round like a ball it appears to be more like a long, skinny potato — or maybe two objects in close orbit around each other, possibly even touching."They also think that there's no debris field around the object, which reduces the chances that New Horizons will crash into a disabling bit of space dust.
OK, that's hot. Looks more like Night of the Duchess to me. And because most of these covers are modeled by real people (remember Fabio?), it'd be great to know who was really on the sofa.
"In other words, the entire point is the assertion and demonstration of the power to say what reality is in contradiction of what is empirically, demonstrably true."That has a lot of similarity to my discussions with climate change deniers, now mostly occurring on Twitter. Because I can empirically demonstrate the truth --- but they get mad at me because they need what they believe to be something other than what's actually true.
